People around the U.S. experienced some internet downtime on Monday. The outage was brief and service has been restored.
The culprit was a configuration issue from Level 3, a telecommunications and internet service provider owned by CenturyLink. In a statement to CNN Tech, CenturyLink said a "configuration error" disrupted service and technicians restored service in 90 minutes.
CenturyLink (CTL) declined to provide further details.
